    摘要: A catalytic cracking catalyst and process which tolerates high levels of vanadium and coke precursors in the feed is disclosed. A zeolite in an alumina free binder or coating, preferably silica, is used as the cracking catalyst. RE-USY in silica is especially preferred as it has a low affinity for vanadium, low coking characteristics and high stability. Preferably a vanadium getter additive is present as separate particles to act as a vanadium sink. The catalyst and process may be used in fluidized bed catalytic cracking (FCC) or in moving bed catalytic cracking units. A method of making a coated catalyst, by adding a layer of an alumina free material to a core of alumina containing cracking catalyst is also disclosed.

    摘要: Methods for preparing phosphorus containing catalysts comprising a large-pore zeolite, e.g., zeolite Beta, zeolite ZSM-12, or zeolite ZSM-20, and a matrix which have improved attrition resistance. The present invention includes the catalyst compositions produced by the above methods. Also included in the present invention are methods for the use of catalysts prepared by the present method in hydrocarbon cracking processes. It is desired to develop cracking catalysts for organic compound conversion that have improved cracking yields and have good attrition resistance. This invention involves the use of large pore siliceous zeolites and a highly siliceous matrix to produce a cracking catalyst with improved cracking yields and good attrition resistance. The invention further involves the use of phosphorus and the use of selected sequences for combining the compounds in the manufacture of the catalyst to enhance the attrition resistance of the catalyst.

    摘要: A catalyst composition which comprises a crystalline metallosilicate having the structure of zeolite Beta, phosphorus, and a matrix that is substantially free of crystalline aluminum phosphate which has improved resistance to steam deactivation and which has higher cracking activity than analogous catalysts prepared without phosphorus. The crystalline metallosilicate may be used in the as-synthesized form or in the calcined form. Also included is the method to produce the catalyst composition and methods for the use of catalysts prepared by the present method in organic conversion processes. Specific embodiments of the invention involve various techniques for preparation of catalysts containing phosphorus and crystalline metallosilicates having the structure of zeolite Beta. Catalysts prepared according to the method of this invention are useful for organic compound, e.g., hydrocarbon compound, conversion processes. Organic compound conversion processes include cracking, hydrocracking, and transalkylation, among others.
